[0054] First embodiment of molding machine 200:

[0055] like Figure 6 , Figure 7 As shown, the frame 6 of the molding machine 200 is equipped with several molding rollers, including textured rollers and mirror rollers. The molding rollers are arranged vertically from bottom to top. The middle molding roller is the middle roller, the molding rollers below the middle roller are the lower rollers, and the molding rollers above the middle roller are the upper rollers. In this embodiment, the frame 6 is equipped with five molding rollers, including two patterned rollers and three smooth rollers. The first roller 1, the second roller 2, the third roller 3, the fourth roller 4, and the fifth roller 5 are arranged horizontally from bottom to top between the two side plates of the frame 6. The first roller 1 and the second roller 2 are patterned rollers, and the third roller 3, the fourth roller 4, and the fifth roller 5 are smooth rollers. The central axes of the five rollers are located on the same vertical plane. The first roller 1 and the second roller 2 are the lower rollers, the third roller 3 is the middle roller, and the fourth roller 4 and the fifth roller 5 are the upper rollers. The first roller 1, the second roller 2, the third roller 3, and the fourth roller 4 have the same diameter, while the fifth roller 5 has a smaller diameter than the other forming rollers. The two ends of the five rollers are connected to the frame 6 through bearing seats, and one end of each roller is connected to an independent drive motor 13, which drives the rollers to rotate.

[0056] like Figures 7 to 9As shown, the first bearing seat 8 of the first roller 1, the second bearing seat 9 of the second roller 2, the fourth bearing seat 11 of the fourth roller 4, and the fifth bearing seat 12 of the fifth roller 5 are movably connected to the side plates of the frame 6, and the third bearing seat 10 of the third roller 3 is fixed to the side plates of the frame 6.

The first limiting device 25, the second limiting device 26, and the third limiting device 27 limit the minimum gap between the second roller 2 and the third roller 3, the minimum gap between the third roller 3 and the fourth roller 4, and the minimum gap between the fourth roller 4 and the fifth roller 5, respectively, to ensure the minimum safety distance between the adjacent two rollers and prevent the adjacent two rollers from colliding and damaging the rollers.

[0057] As shown in Figure 7 , Figure 8 , the first lower sliding rail 14 is vertically arranged on the side plates of the frame 6 corresponding to the bearing seats of the first roller 1 and the second roller 2, and the first lower sliding plate 15 is slidably arranged on the first lower sliding rail 14. The bottom of the first lower sliding plate 15 is connected to the speed reducer of the first lower sliding motor 16, and the speed reducer of the first lower sliding motor 16 is located below the first lower sliding plate 15. The first lower sliding motor 16 is fixed to the frame 6, and the first lower sliding motor 16 can drive the first lower sliding plate 15 to move up and down along the first lower sliding rail 14. The second bearing seat 9 of the second roller 2 is fixed to the first lower sliding plate 15.

The speed reducer of the second lower sliding motor 18 is located below the center of the first roller 1, and the second lower sliding motor 18 can drive the first bearing seat 8 to move up and down along the second lower sliding rail 17, thereby driving the first roller 1 to move up and down to adjust the film pressing gap between the first roller 1 and the second roller 2. When the first lower sliding motor 16 drives the first lower sliding plate 15 to move up and down, the first roller 1 and the second roller 2 can be driven to move up and down synchronously to adjust the film pressing gap between the second roller 2 and the third roller 3. The speed reducer of the first lower sliding motor 16 is located below the first lower sliding plate 15, and the speed reducer of the second lower sliding motor 18 is located below the center of the first roller 1, so that the stress on the first lower sliding plate 15 and the first bearing seat 8 is more balanced, and the cooperation with the sliding rail is more stable and reliable.

[0058] As shown in Figure 8As shown, the synchronous limiting mechanism 24 is arranged between the first bearing seat 8 and the second bearing seat 9, and comprises a limiting rod 241 and a synchronous limiting lifter 242.

When the first upper sliding motor 21 drives the upper sliding plate 20 to move up and down, the fourth roller 4 and the fifth roller 5 can be synchronously driven to move up and down to adjust the film pressing gap between the fourth roller 4 and the third roller 3. The reducer of the first upper sliding motor 21 is located above the upper sliding plate 20, and the reducer of the second upper sliding motor 23 is located above the center of the fifth roller 5, so that the stress of the upper sliding plate 20 and the fifth bearing seat 12 is more balanced, and the cooperation with the sliding rails is more stable and reliable.
